dma: tegra: make tegra_dma.chip_data a pointer to const data 

This prepares *of_device_id.data becoming const. Without this change
the following warning would occur:

	drivers/dma/tegra20-apb-dma.c: In function 'tegra_dma_probe':
	drivers/dma/tegra20-apb-dma.c:1210:9: warning: assignment discards 'const' qualifier from pointer target type [enabled by default]

[ukl: split Laxman's patch to prevent warnings in the middle of the
series. Original patch was sent with msgid
1346217447-19730-1-git-send-email-ldewangan@nvidia.com]
